Contraction of muscle at gastro esophageal junction cardiac sphincter prevents reflux
|
Detailed explanation-1: -The gastrointestinal polypeptide gastrin, found in great abundance in the gastric antrium, was shown in 1970 to have a very dramatic effect in stimulating the smooth muscle segment of the lower esophageal sphincter (LES), and in causing marked increases in pressure in this region.
Detailed explanation-2: -These results suggest that in humans gastrin at physiological postprandial plasma concentrations decreases LESP, does not influence TLESR, but increases the percentage of TLESR associated with reflux.
Detailed explanation-3: -Both hog gastrin and synthetic gastrin stimulate the cardiac sphincter to increase tone and augment the resistance to reflux.
Detailed explanation-4: -Esophagus. The esophagus is a muscular tube that connects your mouth and your stomach. Rings of muscle contract and relax to allow food and liquids to pass through the upper and lower portions.
